What Rob is looking for is this bit in htup.h: /* * MaxAttrSize is a somewhat arbitrary upper limit on the declared size of * data fields of char(n) and similar types. It need not have anything * directly to do with the *actual* upper limit of varlena values, which * is currently 1Gb (see TOAST structures in postgres.h). I've set it * at 10Mb which seems like a reasonable number --- tgl 8/6/00. */ #define MaxAttrSize (10 * 1024 * 1024) The rationale for having a limit of this sort is (a) we *don't* want the upper limit of declarable length to be encoding-dependent; and (b) if you are trying to declare an upper limit that's got more than a few digits in it, you almost certainly ought to not be declaring a limit at all. regards, tom lane -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
